Garage door opener power specs

A garage door opener is rated around 550 W, but the real figure shifts with a few things:

Model and rating: A garage door opener ranges from about 350 W on efficient units to 750 W on larger or older ones — a spread of ~400 W.
Usage: the real draw depends on the material and load you put it under.
Startup surge: the motor can briefly spike to about 1,100 W at start-up, well above the 550 W running figure.
Standby: even idle it keeps drawing ~5 W, which quietly adds up over a year.
Run time: because a garage door opener only runs in short bursts (a few minutes at a time), hours of use matter as much as raw wattage on your bill.
